I have removed the conflicting commit from the printk tree for now.
The patchset has to be reworked. And the new version won't include
nbcon_cpu_emergency_flush().
Sigh, this conflict existed already before 6.11 merge window.
At that time, Paul decided the postpone the RCU change to make the life easier,
see https://lore.kernel.org/r/20240703131820.02eb8021@xxxxxxxxxxxxxxxx
Unfortunately, Linus did not accept the printk changes during the
merge window for 6.11, see
https://lore.kernel.org/r/CAHk-=whU_woFnFN-3Jv2hNCmwLg_fkrT42AWwxm-=Ha5BmNX4w@xxxxxxxxxxxxxx
I am sorry for all inconveniences.
Best Regards,
Petr
